Title: High-efficiency process-heating apparatus
Inventor: YASUOKA SHO
IPC: C10G9/20
Filed: 1993-06-14
Abstract: PURPOSE:To provide a heating apparatus having improved temperature distribution uniformity and reduced apparatus size. CONSTITUTION:Two burners each having a heat-accumulator are used as a set and alternately burnt. A furnace body containing a tube is provided at the base part with an alternate-burning burner having the above burners in a state to set the burners parallel to each other. Combustion gas generated from a burner at the base of the furnace body flows while heating the installed tube, turns 180 deg. and exhausted from the other burner at the base of the furnace body while releasing the sensible heat and recovering the heat with the heat- accumulator. The damper is in closed state during the above process. The combustion is alternately repeated. The temperature distribution in the furnace is uniformized by this process to improve the temperature distribution, reduce the loss accompanying to the exhaust gas and attain energy saving of 30-40% compared with conventional apparatus. Since ideal heat-exchange is performed by the uniformized temperature distribution, the overall size of the apparatus can be reduced. The life of the apparatus can remarkably be prolonged because there is no generation of local hot-part in the apparatus.

Filed: 1977-11-29
Abstract: PURPOSE:To provide a device which is so arranged as to be able to detect the toner concentrations of the developer immediate after finisheng of developing with good responsiveness by disposing a toner concentration detector near the sleeve of the developing device. CONSTITUTION:Magnetic poles 2 are disposed in the range from the position buried within the developer 5 of a developer vessel 4 to the position where they oppose to a photoreceptor 6. Because of this, the influence of magnetic flux hardly appears in the range where the toner having finished developing is flowed in a toner concentration detector 8 by a separator 7. Hence, the interposition of a magnetic shield plate 9 permits disposition of the detector 8 in proximity to a rotating sleeve 1. The toner in a toner replenishing device 10 is replenished into the vessel 4 as the decrease signal to a specified concentration by the detection coil 11 of the detector 8 is transmitted to a replenishing roller 12 through an oscillator, comparator and switching. The influence of magnetic flux on the flow of the developer and the detection  coil is eliminated and the stable concentration detection may be performed.
